In this work, we focus on multiple interactions of hydrogen bondings of adenines as control factors of molecular arrangements. Two one-dimensional manganese complexes, [Mn_2(naphtmen)_2(L)](ClO_4)・2Et_2O・2MeOH・H_2O and [Mn_2(naphtmen)_2(HL)](ClO_4)_2・MeOH were synthesized by using a bridging ligand including a nucleobase moiety, 6-amino-9-β-carboxyethpurine (HL), and salen-type manganese dinuclear complex, [Mn_2(naphtmen)_2(H_2O)_2](ClO_4)_2 (naphtmen^2_=N,N'-(1,1,2,2-tetramethylethylene) bis(naphthylidene-iminato)dianion). Manganese salen-type units, which are out-of-plane dimer bridged by phenoxo groups, are linked by HL ligands thorough carboxylate bridges in syn-anti mode to form one-dimensional chain structure, where each chain is magnetically isolated by hydrogen bondings of nucleobase units. Cryomagnetic studies reveal that both complexes show SCM properties.

在这项工作中，我们专注于腺嘌呤的氢键作为分子排列的控制因素的多重相互作用。两个一维锰配合物[Mn_2（萘）_2（L）]（ClO_4）·2Et_2O·2MeOH·H_2O和[Mn_2以6-氨基-9-β-羧基乙基嘌呤（HL）为桥连配体，与Salen型锰双核配合物[Mn_2]反应，合成了[（naphthmen）_2（HL）]（ClO_4）_2·MeOH（naphthmen）_2（H_2O）_2]（ClO_4）_2（naphthmen ^2_=N，N'-（1，1，2，2-tetramethylene）bis（naphthylidene-iminato）dianion）.锰salen型单元是由苯氧基团桥联的面外二聚体，HL配体通过羧酸桥以顺反方式连接形成一维链状结构，每个链通过核碱基单元的氢键磁性隔离。冷磁研究表明，这两个复合物显示SCM属性。
